As of September 2014, felony convictions stay on record until the person with the felony conviction has it expunged. To get a felony expunged, one must petition the state and/or jurisdiction to destroy or seal the conviction. Each state has its own laws regarding the expunging of criminal records.
Felony convictions and all other criminal records are public. They are available to local, state and federal authorities. The requirements for having a record destroyed or sealed differ from state to state, but are generally very similar. Factors such as completed probation, number of priors, no convictions during waiting period and being free of new arrests are some examples. In some states, such as Florida, a guilty plea of conviction cannot be expunged from public record.
